- SS Cyg, U Gem (dwarf nova)
- BL Lac (Blazar)
- U And, W And, S Cyg (mira variables)
- CY Lyr, TZ Lyr, TT Ari (variables)
- RX And, RZ LMi, U Mon  (variables)
- Z And, RU Peg, DY Per (variables)
- Evening session (5.3hr), operated under automated control for majority of session. Problem performing short mapping job using new TPoint Model
CCD operation of -15 degC (at 52% average cooling). 
-main objectives were to acquire images of certain selected stars of ongoing photometric and astrometric analysis
-opportunity was also taken to acquire gallery images of certain deep sky objects.

UGC 12846 - Spiral Galaxy with Supernova 2007od

UGC 12846 with Supernova 2007od (Pegasus)
Galaxy UGC 12846 is very faint, but the supernova is very clear. 
(Note : stars slightly trailed)
